Protocol Number: 00-HG-0209
Patients with Wiskott-Aldrich syndrome, adenosine deaminase (ADA) deficiency, Janus Associated Kinase 3 (JAK3) deficiency, common variable immunodeficiency (CVID) and other immunodeficiencies may be eligible for this study. Participants will undergo a medical and family history, physical examination, and additional procedures and tests that may include the following: 1. Blood tests for: routine laboratory studies (i.e. cell counts, enzyme levels, electrolytes, etc.); HIV testing; immune response to various substances; genetic testing; and establishment of cell lines to maintain a supply of cells for continued study 2. Urine and saliva tests for biochemical studies 3. Skin tests to assess response to antigens such as the viruses and bacteria responsible for tetanus, candida, tuberculosis, diphtheria, chicken pox, and other diseases. 4. Skin and lymph node biopsies for tissue and DNA studies 5. Chest X-ray, CT scans, or both to look for cancer or various infections. 6. Pulmonary function test to assess lung capacity and a breath test to test for H. pylori infection. 7. Dental, skin and eye examinations. 8. Treatment with intravenous immunoglobulins or antibodies to prevent infections. 9. Apheresis for collecting white blood cells to study cell function. In this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The white cells are then removed, and the red cells, platelets and plasma are returned to the body, either through the same needle or through a second needle placed in the other arm. 10. Bone marrow sampling to study the disease. A small amount of marrow from the hipbone is drawn (aspirated) through a needle. The procedure can be done under local anesthesia or light sedation. 11. Placental and umbilical cord blood studies, if cord blood is available, to study stem cells (cells that form blood cells). Information gained from this study may provide a better understanding of primary immunodeficiencies, leading to better diagnosis and treatment. In addition, study participants may receive medical and genetic counseling and may be found eligible for other NIH studies on these diseases.
